[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, the Peak racket according to an embodiment of this utility model includes an inner core 100, a handle 200 connected to the edge of the longer end of the inner core 100, and an outer core 300. A step 400 is connected to the outer edge of the inner core 100. The two outer surfaces of the step 400 are equidistant from the racket face of the nearest inner core 100. Multiple weight adjustment slots 410 are evenly distributed on the step 400. The outer core 300 is connected to the step 400. This structure, by introducing an adjustable weight design into the racket's main structure, allows users to finely adjust the racket's performance according to their personal habits and actual match requirements. The inner core 100, as the racket's skeleton structure, typically uses high-strength composite materials or polymer foam core materials, ensuring overall structural stability while providing good shock absorption and rebound performance. The handle 200 is connected to the inner core by bonding or integral molding. Its length and grip design conform to ergonomics, ensuring comfortable holding and flexible operation.

[0029] In practical use, by setting a step 400 on the inner core 100 and a weight adjustment block placement slot 410 on the step 400, different outer cores 300 can be matched on the step 400 according to actual needs, and different weight adjustment blocks 420 can be placed in the weight adjustment block placement slot 410, thereby meeting the needs of different users, such as the elasticity of the racket itself, the size of the hitting area, the power of the swing, and the agility of the interception. At the same time, production is more flexible and convenient, and production and replacement costs are lower. For example, by adding or removing weights at key positions such as the 12 o'clock, 3 o'clock, and 9 o'clock, users can effectively change the swing weight and balance point of the racket, thereby adapting to different tactical needs such as fast net play or powerful baseline shots. This design also significantly reduces material waste and process complexity in the manufacturing process, and the supply of outer cores and weight components can be flexibly adjusted according to market demand.

[0030] In some specific embodiments of this utility model, it may also have the following additional technical features: the width of the step 400 is 10mm-30mm. This width range has been verified through multiple mechanical tests and usage, ensuring both the connection strength between the outer core 300 and the inner core 100 and providing sufficient space for the installation and adjustment of the counterweight. If the width is less than 10mm, the outer core coverage area is insufficient, affecting the overall integrity and durability of the structure; if it is greater than 30mm, the overall size of the racket will be too large, affecting the flexibility of handling.

[0031] In some specific embodiments of this utility model, it may also have the following additional technical features: the distance from one of the outer surfaces of the step 400 to the racket face of the nearest inner core 100 is 15%–44% of the height of the inner core 100. This proportional range ensures that the step position is neither too inward, resulting in insufficient support for the outer core, nor too outward, affecting the effective area of ​​the hitting zone. Specific values ​​can be fine-tuned according to different racket face sizes and mechanical models to achieve optimal performance matching.

[0032] In some specific embodiments of this utility model, it may also have the following additional technical features: the number of weight placement slots 410 is three or five. Specifically, with the handle 200 as the 6 o'clock position, the top of the inner core 100 opposite to the handle 200 is the 12 o'clock position, the two sides of the inner core 100 are the 3 o'clock and 9 o'clock positions, and the positions close to the handle 200 and located on both sides of the inner core 100 are the 5 o'clock and 7 o'clock positions; when the number of weight placement slots 410 is three, corresponding weight placement slots 410 are provided on the steps 400 corresponding to the positions at the 12 o'clock, 3 o'clock, and 9 o'clock positions; when the number of weight placement slots 410 is five, corresponding weight placement slots 410 are provided on the steps 400 corresponding to the positions at the 12 o'clock, 3 o'clock, 9 o'clock, 5 o'clock, and 7 o'clock positions. Three-point weighting is suitable for beginners or users who want to increase swing speed, while five-point weighting is more suitable for advanced players who want to make more precise adjustments to their center of gravity. Each slot can be independently configured with metal or non-metal weights of different qualities, such as stainless steel, tungsten alloy, or polymer composite materials, to meet different usage needs.

[0033] In some specific embodiments of this utility model, it may also have the following additional technical features: the length of the placement groove 410 for the adjusting weight 420 is 20mm-100mm. Grooves of different lengths can accommodate adjusting weights 420 of different sizes. Users can stack multiple small weights in the same position or select a single long strip counterweight according to actual needs, thereby achieving a wider range of weight adjustment. The bottom of the groove can be designed with anti-slip texture or fixing groove to prevent the counterweight from shifting during vigorous movement.

[0034] In some specific embodiments of this utility model, it may also have the following additional technical features: the width of the counterweight placement groove 410 is 5mm-12mm. This width can accommodate most standard counterweight bars and facilitates manual installation and removal by the user. If a larger counterweight is required, it can be achieved by increasing the groove depth or using high-density materials without changing the groove width.

[0035] In some specific embodiments of this utility model, it may also have the following additional technical features: there are two outer cores 300, each adapted to be connected to both sides of the step 400; both outer cores 300 are fitted and connected to the outer edge of the inner core 100; the two outer cores 300 and the step 400 form a composite sandwich structure of "outer core 300-step 400-outer core 300". This sandwich structure not only enhances the overall torsional resistance of the racket, but also effectively disperses the impact force generated during hitting the ball. The outer cores and the step can be fixed together by high-strength adhesive or mechanical clips to ensure that delamination or loosening does not occur during long-term use.

[0036] In some specific embodiments of this utility model, it may also have the following additional technical features: the outer core 300 is made of an elastic material with a hardness of 15-40 degrees. Specifically, the elastic material can be EVA, PET, or other commonly used elastic materials in the prior art, which will not be elaborated here. Outer cores with different hardness can provide differentiated hitting feel and ball feedback: lower hardness EVA materials (e.g., 15-25 degrees) provide a softer touch and better shock absorption; while higher hardness PET or modified polymers (30-40 degrees) help improve elasticity and ball speed, suitable for offensive players.

[0037] In some specific embodiments of this utility model, it may also have the following additional technical features: the Peak racket further includes a edging protective strip 500, which covers the outer edge of the composite sandwich structure and the handle 200 connected to the inner core 100. This edging strip not only enhances the appearance but, more importantly, protects the internal structure from impacts and moisture corrosion, extending the racket's lifespan. The junction between the edging strip and the racket body can adopt a streamlined transition design to reduce wind resistance and improve grip comfort.

[0038] In some specific embodiments of this utility model, it may also have the following additional technical features: the thickness of the edge protection strip 500 is 1mm-2mm, and the width is 10mm-20mm. The edge protection strip 500 can be formed by wrapping the structural foam core material with carbon fiber or glass fiber. Carbon fiber edge protection has higher strength and modulus, making it suitable for professional users; glass fiber edge protection, while ensuring sufficient protection, has a cost advantage and is suitable for the mass market. The outer layer of the edge protection can be coated with a wear-resistant coating or textured rubber to further enhance service life and grip stability.

[0039] Specific production and assembly processes:

[0040] An inner core 100 structure with a step 400 is formed on a core material with a diameter larger than the outer diameter of the inner core 100 by wire cutting. Then, a corresponding counterweight placement groove 410 is made on the step 400 of the inner core 100, and a counterweight 420 is placed in the groove 410. Next, an outer core 300 is formed by cutting an elastic material to the same size as the step 400. The outer core 300 is then assembled onto the step 400, forming a composite sandwich structure of "outer core 300-step 400-outer core 300". An edge-protecting strip 500 is then wrapped around the handle 200 and the composite sandwich structure. Finally, the entire structure is heated to 135℃ and cured for 30 minutes to achieve final molding. The production line can use high-precision CNC cutting equipment to ensure that the dimensional tolerance of the step and the counterweight groove is controlled within ±0.1mm. The outer core material is formed into a shape that perfectly matches the step through die cutting or waterjet cutting. Specialized fixtures are used during assembly to ensure accurate alignment of all components. Segmented pressurization and temperature control techniques are employed during the heating and curing process to ensure the adhesive fully cures and the material does not undergo thermal deformation. This process is efficient and scalable, suitable for both large-scale standardized production and personalized customization needs.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
